SM712X

Shenzhen JingYang · ESD And Surge Protection (TVS/ESD) · SOT-23

SM712X from Shenzhen JingYang, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Pin1 bidirectional Protected data line with TVS clamping to pin 3: 12 V working voltage for pin 1 to pin 3 polarity and 7 V working voltage for pin 3 to pin 1 polarity, with 50 pF typical parasitic capacitance.
2 Pin2 bidirectional Protected data line with TVS clamping to pin 3: 12 V working voltage for pin 2 to pin 3 polarity and 7 V working voltage for pin 3 to pin 2 polarity, with 50 pF typical parasitic capacitance.
3 Pin3 passive Common terminal shared by the two 12 V and two 7 V TVS diode paths on pins 1 and 2; the datasheet does not specify it as a ground or supply pin.

  • Symbol: SM712X
  • Footprint: Package_TO_SOT_SMD:SOT-23
  • 3D model: SOT-23 (KiCad packages3D, STEP)
  • 3D model files: sm712x-etched.step / sm712x-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); sm712x.step / sm712x.glb are the bare package body.
